How do you filter your eyes?

a phone and screen filter easy
a button push to hide the unsightly
tap and your bubble grows
Surely our eyes cannot be filtered though
our eyes are eyes that see unwanted glimpses
of gruesome vile images
constantly

Perhaps our eyes have no filter

but we filter subconsciously
for who wants to see
that man on the street
that car on the road
both who we know
sit and plead
but tricksters they may be
until one day we see
no one in need

Our brain filters for our eyes
so we may see all the blue skies
and any cloud that may block our view
can be hidden for our plane of blue

What clouds your eyes
for your blue skies
